€5,600 SEAI grant available

Window & Door Installation Across Ireland

Single glazing, tired seals and old frames account for roughly a fifth of the heat leaving a typical home — and most of the draughts you actually feel.

SEAI grants up to €4,000 for windows and €1,600 for doors. Standalone since 2 March 2026 — a full retrofit is no longer required, though your home must meet SEAI fabric requirements.

Double and triple glazing

Modern A-rated units use low-emissivity glass, warm-edge spacers and argon fill to hold heat inside. Triple glazing adds a further step for exposed or north-facing elevations and for homes on busy roads, where the drop in noise is often as noticeable as the drop in heating cost.

Doors

Composite and insulated uPVC doors seal properly against wind-driven rain, come with multi-point locking, and stop the cold draught that runs across the hall floor in older houses. Frame colours are matched across windows and doors so the elevation reads as one job rather than two.

What the installation includes

Delivery, removal and disposal of the old units, and full installation are included in every quote. Finishing prepared for painting is available as an add-on so the job is left ready to decorate. We measure every opening ourselves, so units fit correctly first time.

Window brands we supply

We don't just install windows — we supply them too. Every unit is manufactured to order by one of our two window partners, so you're choosing from established European profile systems rather than an unknown import.

Germany

Veka

One of the world's largest manufacturers of uPVC window and door profile systems, in production since the late 1960s and operating in more than 40 countries. Veka profiles are manufactured to Class A quality under DIN EN 12608.

  • Multi-chamber profile design for strong thermal and acoustic performance
  • UV-stable and weather resistant — won't warp, fade or discolour
  • Tilt-and-turn systems available to Passivhaus-level performance
  • Low maintenance — no painting or sealing required
Poland

Plastimet

An established window and door manufacturer based in Ełk, Poland, producing PVC and aluminium windows on modern European production lines, sold across Poland and abroad.

  • 6-chamber PVC profile for strong thermal performance
  • HTS-welded corners for long-term structural strength
  • EPDM gaskets for weatherproofing and noise reduction
  • Wide range of colour and wood-effect foil finishes

Plastimet Click-ON: the window we fit most often

Click-ON is Plastimet's in-house modular profile system — a 6-chamber frame with an 80mm installation depth, taking glazing units up to 44mm thick. Corners are welded using HTS (high-temperature) technology for a narrow, strong joint, and hardware is supplied by ROTO NT of Germany, with anti-pry protection and child-safe opening options built in.

The Central Sealing Module is Plastimet's own upgrade — a third seal that clicks into the frame, even on a window that's already installed, without glue or extra screws. It measurably improves the window on four fronts: warmer (the U-value above), quieter, tighter against wind-driven rain, and more resistant to a burglary attempt, since it adds a physical barrier behind the sash.

Click-ON is available in white, brown and grey as standard, plus wood-effect foil finishes — golden oak, walnut, Douglas fir, chocolate brown, anthracite grey, dark oak, light oak and mahogany — with further colours available on request. An R-Line version with rounded glazing beads is also available for a softer profile.

Common questions

Is there an SEAI grant for windows and doors?

Yes. Since 2 March 2026 windows and doors are a standalone SEAI grant — up to €4,000 for windows and €1,600 for doors — so a full deep retrofit is no longer required. Your home must meet SEAI fabric and insulation requirements to qualify, which we confirm at the survey.

Should I choose double or triple glazing?

Double glazing suits most homes. Triple is worth considering on exposed elevations, north-facing rooms and properties on busy roads where noise is a factor.

Do you remove the old windows?

Yes. Delivery, removal and disposal of old units and full installation are included in the quoted price.
